Frankly Speaking

Hello, and welcome to the Abyss.
I just had a telephone conversation with a lady friend of mine. She considers me her therapist, counselor, and adviser. I never thought of myself as a therapist or counselor. I have been told that I am a "good" listener and, in my opinion, an objective adviser is the opposite side of the same coin.
I have noticed a defensive verbal stance when I attempt to define a point or topic within our subject of discussion. She lashes out at me, in my opinion of course, by saying, "GEEZE! You are hard to talk to!"
Ironically she has told me on several occasions that I am able to explain things simply and precisely.
I must admit that she paints herself into a verbal corner and I do not help the situation by blocking her escape routes until she has no recourse but to go right through me. I say "We are all adults here. We should be able to have disagreements in a civil manner!".
End of discussion.
She gets over it and the next morning or a few hours later, depending on the velocity of her "escape" everything is hunky-dory. This is one of qualities that I truly value in my friend--She does not hold grudges.
I am wondering, "Do professional therapists and counselors experience this sort of attack?" I would venture to say that professional counselors "see" the painted corner coming and take the nearest exit. What do you think?
